概覽

AI 產生的概覽

遠端 MCP 伺服器，讓助理依克拉與貨幣查詢黃金、白銀、鉑金、鈀金的即時現貨價，並計算首飾熔值與精確換算黃金重量單位。

可以做什麼: 查詢當日每公克、每金衡盎司、每托拉與每公斤的黃金價格，涵蓋 24K 至 9K 及約 160 種貨幣，並附現貨時間戳與匯率日期
取得黃金、白銀、鉑金、鈀金以盎司、公克、公斤計的現貨價，單一金屬資料來源故障時單獨回報錯誤而不影響整體呼叫
依重量、單位與克拉估算黃金飾品（戒指、項鍊、手鍊、廢金）的熔值，可選經銷商價差以推估買家出價
在公克、公斤、金衡盎司、本尼威特、格令、常衡盎司、托拉、泰銖、越南 chi 與 luong、香港與台灣兩、中國兩之間換算黃金重量
適用情境: 適合使用者詢問目前黃金或貴金屬價格、特定貨幣下的某克拉價格、首飾的廢金或熔值，或在模型訓練資料無法涵蓋的地區性黃金重量單位之間換算時使用。
執行需求: 遠端 Streamable HTTP 端點，不需 API 金鑰、權杖或註冊。可選的本機 stdio 版本透過 npx 執行，需要 Node 20 或更新版本。需能連線至託管伺服器，該伺服器再讀取 gold-api.com 現貨價與 Frankfurter 匯率。

安裝前請注意

價格僅為現貨（熔值）：零售首飾更貴、買家出價更低，工具會在回答中說明。託管伺服器的現貨價可能延遲最多 5 分鐘，匯率為每日參考匯率而非即時行情。純度依名目克拉/24 計算，各地「兩」的公克數不同，需明確所選單位。資料來源故障時工具會回傳錯誤，而非過期數字。

安裝

在 SourceWeft 中

README

gold-price-per-gram-mcp

The live gold price per gram for AI assistants, by karat and currency, with metal prices, jewelry melt value and exact gold unit conversion.

This is a Model Context Protocol (MCP) server. It reads the gold, silver, platinum and palladium spot price at call time and converts it with central-bank FX rates for about 160 currencies. It needs no API key.

Tools

Tool	What it returns
`get_gold_price_per_gram`	Gold price per gram, troy ounce, tola and kilogram for 24K, 22K, 21K, 18K, 14K, 10K and 9K in any currency, with the spot time stamp and FX date.
`get_metal_prices`	Spot price of gold, silver, platinum and palladium per troy ounce, gram and kilogram in any currency. A metal whose feed is down is reported, not fatal.
`calculate_jewelry_value`	Melt value of a gold item from weight, unit and karat, with an optional dealer spread percent. States that retail and buyback prices differ from melt value.
`convert_gold_units`	Exact conversion between gram, kilogram, troy ounce, pennyweight, grain, avoirdupois ounce, tola, Thai baht, Vietnamese chi and luong, Hong Kong tael, Taiwan tael and China liang, with the definition and source of each unit.

Every result has structured JSON, a one-paragraph summary, as_of, source and more (the matching page on goldgramprice.com).

What it knows that your model does not

Today's gold price. Spot moves every minute and a model's training data is months old.
Today's exchange rate for INR, AED, SAR, PKR, EUR, GBP and about 150 more currencies.
Exact unit constants. A troy ounce is 31.1034768 g and a grain is 64.79891 mg by definition (NIST Handbook 44). A tola is 180 grains. A Thai bullion baht is 15.244 g, not 15 g. A kitchen-scale ounce is 28.349523125 g, not a troy ounce.
Karat purity as an exact fraction (karat / 24), so 22K is 91.6667% and 14K is 58.3333%.

Example prompts

"What is the 22K gold price per gram in India today?"
"How much is one tola of 24K gold in Pakistani rupees?"
"I have a 14K chain that weighs 12 grams. What is its melt value, and what might a buyer offer at a 25% spread?"
"Show gold, silver and platinum prices in euros."
"How many grams are in a Thai baht of gold, and in a Vietnamese chi?"

Data sources

All keyless and free to use from a server. Full list with fetch dates in DATA_SOURCES.md.

Spot prices from gold-api.com, the same feed goldgramprice.com uses. Its terms allow commercial use and ask callers not to send several requests per second, so the hosted server caches each price for 5 minutes.
FX rates from Frankfurter, blended from the ECB and other central banks. Cached for 1 hour. Rates update once a working day.
Unit constants from NIST Handbook 44 Appendix C. Karat definition from 16 CFR 23.3.

Limitations

Prices are spot (melt) values for pure metal. Jewellery in a shop costs more (making charges, design, tax) and buyers pay less (refining and margin). The tools say so in every answer.
The spot price can be up to 5 minutes old on the hosted server. FX rates are daily reference rates, not live market quotes.
Purity uses the nominal karat fraction. Real items can be slightly under (legal tolerances) or over.
Regional tael values differ (Hong Kong 37.429 g, Vietnam 37.5 g, Taiwan 37.5 g, China 50 g). Pick the one you mean.
When a price feed is down, the tool returns a clear error instead of a stale or remembered number.

Karat calculators, scrap gold, city price pages and gold price history are on goldgramprice.com.

get_metal_prices

Get precious metal prices

Live spot prices of gold (XAU), silver (XAG), platinum (XPT) and palladium (XPD) per troy ounce, per gram and per kilogram, in any major currency. A metal whose feed is down is reported with its error instead of failing the whole call.

輸入參數currency

calculate_jewelry_value

Calculate gold jewelry melt value

Melt value of a gold item (ring, chain, bracelet, scrap) from its weight, unit and karat at the live spot price, in any currency. Optional dealer_spread_percent returns the likely buyer offer. The result states that melt value is not the retail or buyback price.
